multisig and public key

Question

In order to use addmultisig address, N number of public keys must be provided.

The way to find the public key is to use "getaddresses true" and find a public key from an address where "ismine = true". This means all addresses in the wallet has to be looped through to get a public key.

Is there a shorter way to find a public key simply by giving an address is that already known to be mine?

Answer 1

First, you can use the listaddresses API to get information about a specific set of addresses in a single API call.

Second, you can actually pass addresses to addmultisig, if those addresses are in the node's wallet and it has the public key for them.
